Homemade ketchup is the best, and it is pretty easy to make. I have made this for years and always make sure to make a little extra every year to give as Christmas gifts.
Homemade ketchup does not contain a lot of salt or many of the other ingredients that are added to the brand names. It is very tasty to use in cooking many of your favorite dishes.
This version is done using a crock pot. I get it started late at night and then let it cook and thicken all night long. Then it is ready to put in the jars first thing in the morning.
Step 1: Ingredients
4-5 quarts tomatoes (approximately)
1 medium onion
3 cloves of garlic
1 jalapeno pepper
1/2 C cider vinegar
1/2 C sugar
1 t salt
1 t pepper
1/2 t paprika
1 cinnamon stick
1 1/2 t ground cloves
Pint and 1/2 pint canning jars and lids.
Step 2: Prepare the Tomatoes
Place tomatoes on a baking sheet and broil until the skins begin to turn black. This adds a bit of a smoky flavor to the ketchup.
Puree the tomatoes in a blender. Pour the puree into a crock pot.
Step 3: Prepare All Other Ingredients
Cut onion, jalapeno, and garlic into chunks. Puree in the blender and add to tomatoes in the crock pot.
Add the rest of the ingredients.
Step 4: Simmer the Ketchup
Set your crock pot on high and cook the ketchup for about 10 hrs (allow it to thicken). You can also do this on the stove, but you will need to watch it more closely.
After the ketchup has cooked for a little while, taste and adjust the seasonings to your liking.
Once the ketchup has reduced considerably, you are ready to put it in jars and seal them. The ketchup should be quite thick at this point.
TIP: Don't put the lid of your crock on tightly. Allow the the steam to escape in order for the ketchup to reduce.
Step 5: Can the Ketchup
Sterilize your jars and lids. Once your ketchup has reduced, pour into the jars and put on the lids. Fill the jars to about 1/2 inch from the top and make sure to wipe the rims clean before you put on the lids.
Process the jars of ketchup in a hot water bath for about 15 minutes (bring to a boil and boil for 15 min). Make sure the water covers your jars by at least 1/2 inch.
Once the jars have sealed (you will hear the lids pop), label your jars and you are done!
